Overview

Comprehensive Description

Description of Hartmannella

Locomotive form monopodial with a prominent anterior hyaline zone. Locomotion steady, non-eruptive. Cytoplasm without prominent cytoplasmic crystals but frequently with many small crystals. Often with a contractile vacuole. Mitochondria, of those species examined, sometimes elongate. Forms round, or slightly oval, smooth bilaminar cysts. Glycocalyx thin, some with cup-like surface structures, around 12.5 nm in diameter. Habitat: Widely distributed in freshwater, also marine species. Distinguish from other limax amoebae of the class Heterolobosea, and families Leptomyxidae and Amoebidae by comparing features of the groupings. Many inadequately described species in this genus including type species, H. hyalina (Dangeard, 1900).

Hartmannella

Hartmannella is a genus of Amoebozoa, including the following species:[3]

  • Hartmannella abertawensis
  • Hartmannella agricola
  • Hartmannella cantabrigiensis
  • Hartmannella crumpae
  • Hartmannella hibernica
  • Hartmannella hyalina
  • Hartmannella lobifera
  • Hartmannella vacuolata
  • Hartmannella vermiformis

Hartmannella vermiformis is, however, not closely related to the other members of the genus and has been renamed as Vermamoeba vermiformis.[4]
